Abstract

La présente invention concerne un procédé de traitement d’eau alcaline comprenant les étapes consistant à introduire de l’eau dans un premier compartiment (1), faire barboter du dioxyde de carbone dans l’eau dans le premier compartiment (1), amener les matières solides à précipiter, transférer l’eau avec les matières solides qui ont précipité dans un deuxième compartiment (2), séparer, dans le deuxième compartiment (2), les matières solides qui ont précipité de l’eau, transférer l’eau de laquelle les matières solides ont été séparées dans un troisième compartiment (3), faire barboter du dioxyde de carbone dans le troisième compartiment afin d’abaisser le pH de l’eau, et enlever l’eau du troisième compartiment (3), le pH de l’eau enlevée du troisième compartiment (3) étant plus faible que le pH de l’eau dans le deuxième compartiment (2). Les compartiments sont disposés dans une unité portable unique.
